There are many types of oscillators and many different circuit configurations that produce oscillations. Some oscillators produce sinusoidal signals, and others produce nonsinusoidal signals. Nonsinusoidal oscillators, such as pulse and ramp (or sawtooth) oscillators, find use in timing and control applications. Pulse oscillators are commonly found in digital-systems clocks, and ramp oscillators are...
Multi-wing chaotic attractors are highly complex nonlinear dynamical systems. A new four-scroll chaotic attractor was found by energy feedback controlling method in this paper. Spectral analysis shows that the system in the four-wing chaotic mode has very broad frequency bandwidth, verifying its random nature, and indicating the prospect for engineering applications such as secure communications,...
Computation complexity of a broad variety of practical design problems is known to be strongly depending on an imagination about the particular real-world situation. The contribution is based on the fact that our knowledge of reality is always incomplete. The proposed approach is based on the idea that new knowledge can be gained by comparison using the requirement of consistency of different physical,...
Southern California Edison Company, as well as the other California investor owned utilities are mandated to increase their Renewable Portfolio Standard to 20 percent by 2010 and by the Governor's Executive Order to 33 percent by 2020. When achieved, these types of energy resource assets potentially represent a significant means to meet State energy and environmental objectives. Edison is also embarking...
